Fault Recovery
When a fault is detected by the speed controller, the speed controller will attempt to recover from the fault and
resume normal operation. In the case of an intermittent problem such as a loose wiring connection, the con-
troller
may
be able to recover and operate normally for a while, but the problem should be repaired before
placing the vehicle in service.
Depending on the type of fault, the controller will attempt to recover immediately after the condition clears or
after the accelerator pedal has been cycled (released and pressed again).
The following faults can be detected by the IQ System controller:
HW Failsafe
The armature drive FET’s (field effect transistors) regulate the armature current. If the speed controller
detects a failure of the armature drive FET’s or circuitry, a
hardware failsafe
fault is detected.
